Hello Andy,
Thursday, November 19, 2015
I have 2 Russian vac relays, but only rated to 3kV, plus, my doodlings
show I would need multiple relays, as most vac ones only have a single
pair of contacts. Open to ideas how to simplify this and keep the
number of relays to a minimum. OK about knife switches, but the
convenience of not having to gout in the rain snow and ice is very
appealing. Ideally separate aerials for LF and HF would be best, but
for now, and harmony at home, sharing this one is my favoured
approach. Over to the clever folk and thanks for the replies..... ;)
